Hey all,
I am 15 years old and am in good shape, eat healthy, not sexually active, and have no relatives with/had cancer. Recentley i noticed a small, hard bump on my left testicle. It is not visible but you can feel it. I have an aching pain on JUST my left testicle, and no pain on my right. When I push down on the bump the pain gets worse. Does anyone know what this is. Thanks so much for your help. Please respond soon too.
